During installation, users can have OS/2 automatically migrate existing DOS, Windows, and OS/2 environments, mapping them to the OS/2 2.0 environment. In addition, OS/2 2.0 contains profiles of more than 225 of the most popular DOS and Windows applications. Program objects for those applications are placed in the appropriate DOS or Windows folder on the OS/2 desktop; OS/2 1.x groups are mapped to OS/2 2.0 folders on the desktop. OS/2 2.0 also takes care of the special settings required by a few of the 225 DOS and Windows applications. This migration process also includes the supporting DOS, WIN-OS/2(*), and 16-bit OS/2 device drivers and printer definitions, as well as the other applications on the hard disk.
To help users migrate to the Workplace Shell, the user interface can be changed to look like OS/2 Version 1.3. To do this, an experienced user can issue a command that remakes the OS2.INI file. For specific instructions, refer to Migrating to the OS/2 Workplace Shell. When users are ready to use the Workplace Shell, the experienced user can again remake the OS2.INI file.
